l :FUEL-HEATER.

Specification of Application filed 'lfay 25,

To all 'whom it may concern I, FREDERICK E. MAN- United States, residing at the city of Los Angeles, in the county of IlosvAngeles and State of Czilifornia, have invented new and useful Improvements in Fuel-Heaters for Internal-Uombustion Engines, of which the following is l a specification.

My invention relates to that class of internal combustion engines in which hydroA carbons of high specific gravity, such distillate is used as fuel.

It is a well known fact that hydrocarbons of high specific gravity such as distillate Vwhen used as fuel for internal combustion engines require to be heated to a considerably higher temperature than fuels of low specific gravity such as gasolene in order to be properly ignited and exploded in the cylinders and that great difficulty has been heretofore experienced in utilizing such fuel owing to the inability of properly heating such fuel. ,y

' It is the object of my invention to provide means to obviate the above noted obl v j jections, which will be ycheap and simple vin construction and which can be easily and quickly positioned for use upon an explosion engine without materially altering the same.

Another object is to provide means whereby the temperature of the fuel may be regulated as desired.

A further object is to provide a heating means for the above purpose which can be operated without any additional cost other than the initial oost of installation.

I accomplish these objects by the mechanism described herein and illustrated in the accompanying drawings forming a part hereof in which:

Figure 1 is a side elevation, partly in section, of the intake and exhaust manifolds and carbureter of an internal combustion engine with my device attached thereto. Fig. 2 is a perspective view of the dellector. Fig. 8 is a perspective view of a modified form 'of deflector.

In the drawings 5 is the exhaust pipe, 6 the intake manifold and 7 the carbureter of an internal combustion engine of any approved construction. In the exhaust pipe 5 at any convenient point is .provided a threaded port 8 into which is screwed a delector 9 which deflector extends partly in- Letters Patent- Patented Nov. 17, 1914.

side and partly outside of the exhaust pipe Delector 9, as best shown in Fig. 2, is preferably formed of an ordinary pipe nipple of suitable diameter and length which has a portion of one end cut away at the side thereof leaving a projecting or deflecting portion or wing 10 extending into the exhaust pipe 5. An ordinary pipe L 11 is screwed onto the end of the deflcctor which projects outside of the exhaust pipeand has its other end connected to one end of a flexible pipe or tube 12 the other end of which is connected to one end of the vaporizing tube 13. `Vaporizing tube 13 is preferably a piece of brass tubingr of suflicient length to extend longitudinally through the intake manifold G centrally thereof, and projects a short distance outwardly from each end. The outer projecting end of tube 13 is in threaded connection with the intake manifold at l-l and is provided with a pipe L 15. Pipe L 15 is provided with an outlet pipe 1G which extends downwardly to any convenient point. The inner projecting end of tube 13 is passed through a bushing 17 which bushing 1s in threaded connection with manifold 6, to its connection with the end of {lexible tube 12. A butterfly or other valve 18 is provided within tube 12 to partially open or close the passage therethrough and is operated by means of a flexible wire 19 which wire extends to a suitable connection at a convenient point of operation.

In operation with the parts in the position shown in the drawings the exhaust gases as they pass throu h exhaust pipe 5 will have a part thereof deflected by deflcctor 9 into and through tube 12, through vaporizing tube 13 and thence through pipe 16 to atmosphere. .As the exhaust gases pass through vaporizing tube 13 said tube will be heated thereby-and the fuel which is drawn from the carbureter by the suction of the engine will impinge upon or strike against said tube and will be vaporized or heated. Valve 18 is opened or closed to regulate the flow of the exhaust gases through tube 13 thereby supplying a greater or less amount of heat as required While I have shown and described ma preferred Form of instruction it will bc understood that I do not limit myself to such construction.

Fig. 3 shows a modified form of dcflectoiz Having described my invention what 'l claim new and desire to obtain'by Letters Patent is.

l. A fue] heater for internal combustion engines romprising a deflector securedt-O the exhaust pipe of the engine, said defeetor extending partly within and partly without the said exhaust pipe; a tube extending longitudinally and centrally through the intake manifold between the carbureter and the cylinders, having one end thereof open to atmosphere; a connection between said deflector and the other end of said tube.
